Thanks for the excellent feedback so far. I wanted to point out one thing in the continuing discussion. Despite the best intentions and us being engineers and all, it may not actually be possible to write a full spec that accurately defines what is and what is not harassing behaviour. E.g. photography. I think Don had it right in the case that he described, but it would have been hard to write that down before even hearing about such a case. Hence judgment needs to be applied by the ombudsperson & the rest of the IETF management. Jari
